Application filed June 24,

My invention relates to a dust arrester for vacuum and pressure systems to clean the dust from the air being adapted to be operable with sand blasting equipment and hoods 5 where sandblasting is accomplished to take the air out of the sand blasting hood and directed to my dust arrester in a manner to clean the air of the dust and sand and to also be operable readil with vacuum type 0 of dust arresters to co lect the dust within my dust arresting hose bag means and dust arrester in a very efiicient and desirable manner.

A feature of my invention resides in a 15 dust arrester having a series of hose bag cleaners operable to provide a long continous tubular bag-like dust arresterthroagh which the air may escape, the tubular bag members collecting the dust within the same n and having a long continuous formation extending up from the base of the dust arrester which collects the heavy dust in the bottom of the arrester which is continually shaken down from the hose bags which extend up in long continuous U-like members.

It is a feature of my dust arrester to provide a long tubular hose-like ha of cloth or'textile material which is ma e from a strip of cloth folded and sewed to form a 0 long tubular hose-like bag to provide a Simple and economical dust arrester bag that can be readily made into the desired tubular formation of the desired size without necessarily being woven in a tubular formation but be- 5 ing made from the flat strip of cloth folded and sewed with a longitudinal seam.

It is also a feature of my invention to provide a dust arrester of a tubular U-shaped nature with means for supporting the ceni0 tral upper'portion of the same by equalizing means which permits the end of the tubular arrester to depend equally from the equalizer on either side thereof; A further feature of the invention resides in means for operating the equalizing member to shake the dust arrester tube to cause the dust which may collect upon the walls of the same in the operation thereof to fall down to the open ends of the tubular collector and be 50 deposited in a dust collector base. It is 1929. Serial No. 878,155.

also. an important feature of my invention to provide a means of fastening the free ends of my dust arrester bag or tube to collars which are adapted to hold the ends of the dust arrester bag or hose members wide open and having a beaded annular edge over which the bags are adapted to slip to permit a straplike band to extend about the collar below the beaded edge of the same and engage the tubular bag to securely fatsen the same thereto to form a tight joint and yet to provide means to permit the ends of the ba to be easily disengaged from the spreading collars.

A feature of my dust arrester resides in .means for supporting the upper end of the dust arresting bag by a triangular equaliz-. ing block means which connects with a spring rod for suspending the equalizing block and to take up the inequalities in the length of the bag inthe dust arrester. This equalizing means may be also accomplished by a circular wheel-like member engaging the top or middle portion of the tubular dust arresting bag, together with the spring supporting rod. Suitable shaking means is provided for shaking the accumulated dust inside of the bag to deposit the dust in a collector belo the ends of the same. Y 1

These features and others will be more fully and clearly hereinafter set forth in the specification and claims.

In the drawings forming a part of my invention: a

Figure 1 illustrates a perspective view of my dust arrester with the series of dust arresting tubular or hose-like bags extending upward in the same.

V Figure 2 illustrates a detail showing one means of supporting the hose-like bag dust arrester which forms one of the dust arresting bagsin my dust arrester.

Figure 3 illustrates another method of supporting the hose-like dust arrester'bag.

Figure 4 illustrates an enlarged detail in section showing the attachment of the free ends of the tubular dust arresting bagto show the attachment to the dust collecting base.

Figure 5 illustrates diagrammatically the sewing of the flat strips into a tubular formation to provide a tubular or hose-like dust arresting bag.

Figure 6 is a cross section through the bag in enlarged formation to show the relative sewing along the side with the longitudinal seam and body of the bag in transverse cross section.

My dust arrester A is formed with a suitable frame portion B which is adapted to provide a means of supporting a series of dust arrestin tubular or hose-like bags C.

The ust arrester A is provided with a dust collecting base D which collects the dust within the base of the dust arrester A and receives the accumulated dust from the dust arrester bags C when the bags are shaken and the dust is caused to fall down out of the open ends of the bags C. A suitable clean out opening 10 is provided in the dust collecting base. This base is preferably positioned below the open ends of the dust collector bags 0..

An inlet tube 11 is provided for forcing the dusty air into my dust arrester A so as to direct the same up into and out of the cloth dust arrester bags C. Obviously the bags C may be operated to be used equally well with a vacuum in cases where a vacuum cleaning system is desirable. The illustration however, shows the preferred operation with the pressure where the dust air is introduced through the tubular mem er 11 and forced up out of the bags C. The dust will collect on the inner sides of the bags C and by means i economical manner.

which will be hereinafter described, the dust is shaken off into the compartment D in the lower portion of the dust arrester A.

The hose bags C are formed by tubular cloth bags 12 which are of a lon continuous nature either formed by a tubu ar Weaving of the material to forma hose-like cloth dust arrester bag formed in a simple and These bags may be formed bytaking a piece of textile material which is flat and folding it so that it can be sewn with a lon itudinal seam 13 extending along the side 0 the tubular bag 12, thereby forming a tubular dust arrester bag in an economical manner.

My dust arrester A is adapted to be used where it is desirable to clean a large amount of dusty air so that the arrester can continue to operate for a long period without particular attention or the cleaning of the parts or the bag or even the cleaning out of the dust arrester. To accomplish these features efiiciently it is desirable to have long continuous dust collecting bags having a large area by their long continuous formation for the escape of the clean air and yet collecting all of the dust in an efiicient and desirable manner. I accom lish this by the long tubular dust collector ags of a hose-like or tubularlike formation such as C. These bags are adapted to be held with their ends 14 connecter over the attachin collars 15 which are formed with an annu ar means 16 about the up er end of the same to form a shoulder dust collector base so that any dust collected by the bags C will be easily passed out through the collars 15 by reason of the collars 15 holding the ends of the bags C wide open. The attaching means, as just described, by the collars 15, the annular shoulder 16 and the strap 17 provide a means of at taching the open ends of the bag C in such a manner as to permit the easy attachment and removal of the ends of the bag when it is desired. 1

My dust arrester is provided with an equalizing means in the form of the triangular block 20 which engages the bags C centrally between the ends thereof and the equalizer 20 is supported by the rod end 21 of the spring 22 which pivotally engages at 23 through the block 20 by the portion 24 of the end of the rod 21. This pivotally supports the equalizer block 20 to hold the center'portion of the bags C so that an equalizing supporting means is provided between the ends of the bag C. This equalizer supporting means included in the block 20 and the spring 22 provides a means of holding the mid portion of the bags C projecting up and down in the dust arrester A so that a multiplicity of bags C may be used in a small space to provide a large cleaning area by the tubular hose-like bags C in a very small compact dust arrester such as is illustrated in my dust arrester A shown in Fig ure 1.

The spring 22 places a slight tension on the bags centrally between the ends by the equalizer 20 thereby holding the bags C stretched upward in the arrester A. The tension of the spring 22 is just sufiicient to hold the center portions of the bags upward and in position in the arrester so that when the air pressure is off the bags, they will not drop down in the arrester but they will be held upward always in the right position and also to place a slight tension on the same so as to hold the dust arrester bags C so that they may be operated by the shaker means to shake the dust which accumulates on the inside of the same in the operation of the dust arrester A.

The shaking of my dust arrester A is accomplished by the engagement of the rod 21 by the transversely extending members 25. These bars 25 engage across the upper end as dustarrester A as illustrated in Figmay be power operated to continue to shake the bars 25 in a manner to continue the shakv in operation during the operation of the 'dii st arrester A. The power 0 rating shakor means is not illustrated net is may be accomplished in any suitable manner by. power operated means which vibrates or shakes the bars 25 back and forth, i'n'a manner to shake the rod 21 and thereby shaking the upper looped ends 12' of the ags G. v

In Figure 3 I have illustrated a roller 29 which is' pivoted to the portion .24 of the rod 21 of the spring 22 in a manner so as to provide a roller e ualizer 29 for the upper looped ends 12' of t e bags C. This permits the upper or looped ends 12' of the bag to be equalized in relation to the depending portions extending downward from the looped portion 12.

My long tubular dust collector bags C provide a very eflicient means of operating a dust arrester for sand blasting cabinets and which are particularly adapted to draw the dusty air out of the sand blasting cabinets and introduce it into my dust arrester A through the tubular introductory pipe 11 blowing the dusty air up into the bags C and these bags are adapted to accomplish the cleaning of the air in a very eiflcient manner being designed to operate for a long period of continuoususe so eificiently as to thoroughly clean the air and permit the air to pass out of the same virtually free of dust. Without the long tubular cleaners C this could not be accomplished. Thus, by means of the virtually U- shaped tubular cloth or textile cleaning bags C, together with the shaker means and the collector D, I provide a means of accomplishing the arresting of dust efliciently and in a manner in which the dust arrester may be operated continuously for a long period of time and to clean a large volume of air with little or no attention for a long period of time, i
